It looks super cool, but I don't really like the scene... I feel like this series, starring a girl who obviously is more interested in friendship than love (stated in many books), is turning into a love story.
Okay, coding. First of all, the coding language that we're using is heavily modified HTML. It's mostly normal HTML, but there are lots of things that wouldn't be seen elsewhere with this version. A few basic things to start (which might make 0 sense as of now):
You use carrots for your tags (<>)
To close a tag, you use a slash (</>)
You must close your tags, although there are a few exceptions
With coding, you'll either want to basically live in templates, or set your default editing to source mode. (I do both) If you don't, you won't be able to edit your coded messages, so I suggest setting the default to source mode when coding, then switching back. (to change it, hover over your profile pic at the top of the screen, and click preferences. Then, go to the "editing" tab and change the "preferred editor" to whatever you need it to be)
Also, the above is an example of closing a tag. Here, I'll emphasize the closed tag
<nowiki>the code in here wouldn't happen, it would just be viewable</nowiki>
The </nowiki> is a closed tag. All you have to do is repeat the first tag, but put a slash before it. If you're going to do font or div or span tags, it's a bit different, but I'll go over those later.
